rv: Fix missing mutex unlock in rv_register_monitor()
If create_monitor_dir() fails, the function returns directly without
releasing rv_interface_lock. This leaves the mutex locked and causes
subsequent monitor registration attempts to deadlock.
Fix it by making the error path jump to out_unlock, ensuring that the
mutex is always released before returning.
